The Vector Smart Watch is one of our favorites, and not just because it has an official app that works with Windows Phone 8.1 and Windows 10 Mobile. Recently the watch itself got a firmware update, along with the app, that adds some new features and improvements.
"We're excited to publish Facebook and Twitter: you can get your latest Facebook updates, and know all about your tweets and followers at a glance. You can now review your activity data by using the new activity chart - just rotate your phone on the app activity screen. Your activity data and profile are now backed-up on the Vector cloud. We've also made sure we enhanced your calendar event function, as well as improved our over the air update."
You can purchase the Vector starting at $299 from its website.
